Petunia plant named ‘Brevt’

ABSTRACT

A distinct cultivar of Petunia plant named ‘Brevt’, characterized by its uniform cascading plant habit; freely and continuous branching; and numerous blue purple and white bi-colored flowers.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Petunia plant, botanically known as Petunia×hybrida, and hereinafter referred to by the cultivar name Brevt.

The new Petunia is a product of a planned breeding program conducted by the Inventor in Beni Zion, Israel. The new Petunia originated from a cross made by the Inventor of a Petunia selection identified as K-27, not patented, as the female, or seed, parent with a Petunia selection identified as K-51, not patented, as the male, or pollen, parent. The new Petunia was selected by the Inventor in 1997 on the basis of its bi-colored flowers.

Asexual reproduction of the new cultivar by terminal cuttings taken in Poland since 1998, has shown that the unique features of this new Petunia are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Brevt have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, daylength, and fertility level without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Brevt’. These characteristics in combination distinguish ‘Brevt’ as a new and distinct cultivar:

1. Uniform cascading plant habit.

2. Freely and continuous branching.

3. Numerous blue purple and white bi-colored flowers.

Plants of the new cultivar differ primarily from plants of the parent selections in flower color.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which more accurately describe the actual colors of the new Petunia. The photograph comprises a side perspective view of typical flowering plants of ‘Brevt’ grown in a window box.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used. Plants grown in containers were used for the following description. Plants were grown under conditions which closely approximate commercial production conditions in Beni Zion, Israel, during the spring in a greenhouse and were about 3 months old.
